PROBLEM TO BE SOLVED: To provide a fixed abrasive grain wire saw, capable of securing sufficient abrasive grain holding force, achieving excellent machining efficiency and machining precision, and providing long service life and excellent productivity. SOLUTION: In the fixed abrasive grain wire saw 1, a number of abrasive grains 3 having conductive coating 3a on the surface are fixed by metal plating 4 by electrodeposition on the outer circumferential surface of a core wire 2 that is almost circular in cross section, having high strength and conductivity. The metal plating 4 is formed of a first plating layer 4a on the inner side, and a second plating layer 4b on the outer side. The hardness of the second plating layer 4b on the outer side is smaller than the hardness of the first plating layer 4a on the inner side. COPYRIGHT: (C)2009,JPO&INPIT |
